If you test at 1866, and it doesn't pass, loosen the REF cycle time a bit, and see if that helps. For whatever reason I've had to run it up into the 170's for stability on a couple of 1866 kits. You also have a bit of room to increase VTT if needed. Just a suggestion not related to memory. Bring that vcore down. You should not need 1.4v for 4.5ghz. Try 1.35v. It will help with temps, which are rather high. I'd also refrain from running "semi fanless" while stability test. You can use all of the airflow you can get. One you are stable, and not running a constant load, you MAY be ok with limited airflow. I try to keep the temps down in the high 60's and low 70's for testing.

If you test at 1866, and it doesn't pass,When I get MemTest? or is XTU still good test? loosen the REF cycle time a bit, and see if that helps. For whatever reason I've had to run it up into the 170'sThats what's wierd I noticed that XMP 2133 loads 171, but 1333~ 1866 def's to 150, but it worked for the 1 hr last nite for stability on a couple of 1866 kits. You also have a bit of room to increase VTT if needed. Just a suggestion not related to memory. Bring that vcore down.Thats the crazy issue, I dont even have ANYTHING to set that's 1.400,
It's all one thru the newest BIOS from Intel, it wont even llow me to change VDroop any more it's greyed out on Power Saving[ shipped BIOS was able to change] You should not need 1.4v for 4.5ghz.

I know alot of the temp issue is with my "modded" issue with the Ninja,
I got the killer SanAce diredtly on it now see u all after workEDIT..........................................................................
Volts and temps down
9.9.9.24 Stable
Still tried to post w/2133 divider no go

Is this RAM????!!!!!
I got the shit knocked outta me AGAIN
AND at the SAME store as in 2008
This time I spent 5 hrs in the ER
About 2 seconds later and my wife woulda died, as she would have been getting in that door
I'll get back to ram tweaking soon {I hope}

Man. That's almost too real, as I've got a black NISMO, just a year older, I think. Good to hear you and your wife made it out ok.

Sadly it's a new 2011
We traded my 25,012 mi Silver '08 CC NISMO [09 up is PRO4x] in last year on this 2011
I only got 5600 mi on it since last March and well crap !!
I miss the NISMO, because of only a 40% to 27mph throttle restriction vs the 60% 37 mph placed on the 2009 up v6, but I get better MPG
To top insult off, the NISMO was totaled in the massive toronado here last May
It's messed me pretty good this time [again]

BTW is the screenie too blurry to make out?
Hopefully the next week or so i'm home we can get to 2133

OK Guy's here's a screenie of what I have to change around that might help you to spot the "culprit"
Thank you VERY much for trying to work thru this with me!
My biggest regret is that I just cant seem to comprehend what the "Rocket" engineering naming INTEL uses in the EXTREME's BIOS's!!
I know that it's better to have the OP's try to understand WHY and for WHAT it is they are doing, it's just i'm not understnding it

can I see your voltage page. It seems through most of this I seen VTT advised. I see you changed SA which isn't the same thing. Just guessing from what I can see, I'm leaning toward the Processor I/O voltage may be the VTT on that board. Being set at 1.1V is stock for my VTT, so that is why I am making the assumption before I see the voltage page.

Also in BIOS I have an option to change MEM REF VOLTAGE(PROCESSOR)
MEM D.Q. Ref VOLTAGE Chan A Chan B

What exactly does "failed" mean with that software? Why not use Memtest86+ (bootable ISO) or even IBT so you can get a causal BSOD, or the errors in the test that fails with memtest.

I would do one thing at a time here. From those screens I see that the 1333 timings are higher than the 1866 timings. The board is showing me that the timings alone for 1866 are why it wont boot, but paul and I believe dave already addressed this too.

Lets work on one thing at a time so we can see why it fails, or where it fails, so we can get it sorted instead of playing hopscotch with settings

I just tried swaping ram slots, kinda weird thing was
Using XTU, selected XMP {=2133 1.5v} placed CMD to 2, Applied changes.
Now this was the first time that it did a complete "soft" boot using any 2133 or XMP. Always before it did a complete power down then restart, or enter an un-even "hard" boot of differant timings off on, off onnnnnnnnnnn, off onn, off

I'd use the Back to BIOS button then boot at defaults, if it did not restart after 3 cycles.

At any rate that was a good suprise that it almost took 1 time with 2133...
The yellow is what "failed to apply"

I see some ripple in the PSU 12v & 3.3v but not sure if its a concern yet.
12.1260-12.2120 3.3760-3.4080

Dave and I agree about a lot, but I think our methods of overclocking differ somewhat. I like to try one thing at a time to stabilize the cpu or ram first, and rule out/isolate trouble areas. From previous conversations, I think Dave follows the all at once method. I'd try both methods, and see whatever works best for you.

So from all of the fantastic skills here, I looked over alot of the timings for the Samsung's and tried to get a feel for setting mine.
I guess I must not be too far off! BUT, I see that the 4x4 set may have a small price. I bumped bCLK to 102 mem=1900, still took a small hit,
but seems i'm stable with some faster sub-timings than others[granted I have not "focused" on 4x4's] just glancing over some of the posted screenies

From the quick test I wonder if I should just send the Mushkin 2133 back, and take a chance on keeping the Samsung?

Really, got 2x ram for less and so far, neither 1 will touch my 2133
Those comps side by side are too close to say the Mushkin is any better right?

I just did IBT max, passed just as the mushies, XTU stress, passed the same, and for the hell of it tossed in Aiada64 Stress with the other 2 at the same time, did 15 minutes and it's good so I think mabey cut my losse's now and move along??????

I still cant get over how awesome it is on snow, 3-4ft was nothing!!!!

I love the 1 off wheels the NISMO and PRO4x get, it really sets them off
TBH I kinda miss all the chrome, but the all black "stealth" look is sweet.
My body shop have to ship the PRO4x to the dealer to have the dash and special electronics removed before they can start to do the repairs, so i'm gonna have the new tire[they have to refill the nitrogen in the tire] and other 3 reversed to black out
